VEHICLE-TIRE.

To. all whom it may concern:

Be it known that we, LEONARD E. CLAW- SON and FREDRIOK L. Dow, residing-in the city and count of San Francisco and State of California, have invented new and useful Improvements in Vehicle-Tires, of which the following is a specification.

Our invention relates to improvements in vehicle tires having in .view the production of a tire with'sufiicient elasticity to relieve the jar and shock of road-travel; and at the same time of such a character that it cannot be rendered inoperative by puncture, or other similar accident.

It consists in the eculiar construction of the tire, and in detai s of construction which will be more fully explained by reference to the accompanying drawings, in which Figure l is a partial elevation of a wheel and tire partly 1n section. Fig. 2 is an end view of one of the sectional supports. Fig. 3 is an end View of one of the sectional supports in a compressed position. Fig. 4 is a orizontal section on the line ac-w F ig. 2. Fig. 5 is a perspective view of a sectional support, showing the end opposite that seen in Fig. 2. Fig. 6 is a sectional perspective on the line y-y Fig. 5.

It is the object'of our invention to provide a tire which is especially designed for use upon automobiles, and generally for heavy vehicles such as are employed for transportation of goods. I

It consists essentially of an interior sectional support A, which may be inclosed in any suitable outer casing as at B having flan es or other means for securing the who e to the vehicle wheel.

Suitable slots/or channels 2 are'made in the solid rubber or elastic material of the section A, these slots being normally of substa ntiall plano-convex form and they extend entirely throu h the part A in a longietween the slots is left a web portion 3, Whichremains attached along its long sides to the part A, said web portion bein concaved transversely as shown at 4. s shown, one end of the part A, which is adjacent to the opposite end of I Specification of Letters Patent. Application filed December 4, 1908. Serial No. 465,935.

the next block, is provided with a V-shaped groove 3, the part inclosed by this groove standing opposite to a centraldepression 4 in the next adjacent section A. The com.

plete tireis made up of these sections Aa'nd they are designed to fill the outer .casing B from end to'end; The outer casing is than webs 3 with the recesses 4 madein them also provide for a certain amount of yielding in the direction of their length; also while the web unites certain portions of the same section, the whole section is sufliciently elastic and yielding to provide a suitable bearing for vehicles of this kind.

Having thus described our invention, What we claim and desire to secure by Letters Patent is 1. In a vehicle tire, sections ada ted to fit the periphery of the wheel, each 0 ea. sections having an internal transverse web whose opposite ends are separated from the corresponding walls of the section to form channels which are adapted to assume a. concavo-convex form when pressure is applied to the tire.

crable yielding and elastic movement. The

tions having a peripheral form of the required shape of the tire, and ends meeting to form a continuous circumferential tire, said sect1ons having normally plano-convex open" slots made in each side and extending throughthe material of the sections aroun the wheel, and transverse webs between the outer walls of said slots having their ends forming the inner walls of said slots, and having their intermediate portion connected to the body of the section.
